I think mine might only be about 30 years old. It's a piece of stainless steel flatware - a fork. I took it to college with me (originally the fork was from my parent's home) as my in dorm eating utensil and still have it and use it semi-regularly (once every few days) to eat.

The Henckels knives and Farborware cookware I bought when I graduated college in 1982 get use every day. The oldest hardware I use semi-regularly is my mothers pressure canner several times each year from 1957 and the meat grinder that goes back another generation to the late 30s.
